Abstract: Objective To investigate the happening and ways of motor vehicle collisions. Methods Marks involved in motor vehicle collisions were compared and analyzed by trace evidence examination methods. Results Methodologies of mark detection and comparison were summarized. Conclusion Motor vehicle collisions could be identified by examination of vehicle marks， body marks， micro-materials and trace evidence.

Key words: traffic accident, motor vehicle collision, trace evidence examination
